Answer:

2)  Equation 1 and Equation 2 have the same number of solutions.

Step-by-step explanation:

The two given equations are

1)  15x + 6 = 41                and                   2) 2x + 13 = 28

Solving both equations, we get

Solving (1) :   15x + 6 = 41 ⇒   15x  = 41 -  6 = 35

or, x = 35/15 ⇒ x = 7/3

Solving (2) :   2x + 13 = 28⇒   2x  = 28 -  13  = 15

or, x = 15/2 ⇒ x = 15/2

So, from above solutions we can say that Equation 1 and Equation 2 have the same number of UNIQUE solution.

A 15% tax is to be applied to a $120 pair of shoes. Find the total price.
postnew [5]

Total cost of item = $138

Explanation:

The tax percentage = 15%

cost of item = $120

sales tax = cost of item × The tax percentage

sales tax = 120 × 15%

=120 × 0.15

sales tax = $18

Total cost of item = initial cost of item + sales tax

Total cost of item = 120 + 18

Total cost of item = $138
